Study TitleLipidomics of brown adipocytes treated with d9-choline
Study Typetargeted LC-QTOF/MS lipidomic profiling
Study SummaryBrown adipose tissue (BAT) was initially characterised as a thermogenic organ, and recent studies have suggested it plays a crucial role in maintaining systemic metabolic health. In this project, we demonstrated that alteration of BAT function contributes to development of heart failure through disorientation in choline metabolism. To analyze the detail effect of choline accumulation on brown adipocytes, we conducted the LC-QTOF/MS analysis using cultured brown adipocytes treated with d9-choline. In brown adipocytes treated with d9-choline, we found increase of phosphatidylcholine and lysophosphatidylcholine, suggesting that choline was metabolized in healthy brown adipocytes.

MS Comments:Mass spectra were acquired at the rate of 1.5 cycles /sec over an mass range of m/z100–1,700. The reference masses of reference standards were 121.050873(Purine) and 922.009798(HP-0921) for positive ion mode, and 112.985587(TFA) and 1033.988109(HP-0921+TFA) for negative ion mode. Raw data from LC–TOFMS were processed using Master Hands ver. software for the quantification of lipids.
